The utility model belongs to the technical field of the lower-bearing hanging blue construction. In order to solve the problems that the hanging basket can't walk smoothly when the lower-bearing hanging blue closure section is constructed, the beam body can't retreat smoothly after completion of pouring, and the tower crane can be demolished, a construction device for the walking and retreating of the lower-bearing hanging basket closure section is provided, including double hook beams and supporting columns, and the setting of double hook beams spanning the pouring beam body. The two supporting columns are symmetrically located on both sides of the casting beam, and the top of the supporting column is connected with the middle cross beam of the supporting double-hooked beam, and the bottom support of the supporting column is connected with the hook tail of the corresponding side double-hooked beam; the hook tail of the double-hooked beam is connected with the outer guide beam truss of the undercarriage basket; the lower part of the middle cross beam of the double-hooked beam is connected with two sliding rails which can slide along the top surface of the casting beam, and the two sliding rails are longitudinally along the casting beam body. Set symmetrically. The utility model realizes the smooth running of the closing section of the through-type hanging basket, ensures the smooth retreat and demolition of the through-type hanging basket after the completion of the beam construction, provides the construction work efficiency, and has remarkable economic benefits.
【技术实现步骤摘要】
一种下承式挂篮合拢段走行及后退拆除施工装置
本技术属于下承压式挂蓝施工的
,具体涉及一种下承式挂篮合拢段走行及后退拆除施工装置。
技术介绍
挂篮悬臂浇筑施工又称迪维达克施工,因其采用挂篮施工结构简单、受力合理及一次移动到位,无需搭设支架不妨碍桥下净空及正常交通等优点使得悬臂浇筑法应用的最为广泛。现行下承式挂篮施工中存在多种问题,一是,现有下承式挂篮无法实现梁体合拢段的顺利施工,不能行改装挂篮在合拢段处无法前移;二是,下承式挂篮在完成梁体施工后,拆除困难,后退施工困难,墩高吊车无法进行吊装拆除等多种问题。
技术实现思路
本技术为了解决下承式挂蓝合拢段施工时,挂篮不能顺利走行到位,梁体浇筑完成后不能顺利后退、塔吊拆除的难题,进而提供了一种下承式挂篮合拢段走行及后退拆除施工装置。本技术采用如下技术方案:一种下承式挂篮合拢段走行及后退拆除施工装置,包括双勾梁和支撑柱,双勾梁横跨浇筑梁体设置,两根支撑柱对称设于浇筑梁体两侧,支撑柱的顶端连接支撑双勾梁的中部横梁,支撑柱的底部支撑连接于对应侧双勾梁的勾尾上;双勾梁的勾尾与下承式挂篮的外导梁桁架连接;双勾梁中部横梁下方连接两根能沿浇筑梁体顶面滑行的滑轨,两根滑轨沿浇筑梁体纵向对称设置。所述双勾梁的勾尾上水平安装有推移油缸,推移油缸的缸体固定于双勾梁的勾尾上,推移油缸的活塞杆端头推移顶紧支撑柱底部。因浇筑梁体可能为变截面,可利用推移油缸调整支撑柱的横向固定位置,以避免和梁体干涉。所述双勾梁的横梁至少高出浇筑梁体顶面50cm,以留出滑轨安装以及后退移动的空间。本技术是通过双勾梁结合C梁来承受挂篮重量,支撑柱用于支撑双勾梁, ...
